In various areas there are holes in the planet earth that exist naturally, they may have been created by the activity of the earth’s crust or by asteroids that fell from outer space, but there are also others that have been dug by man in his insatiable search for mineral wealth.
In the last ice age, a limestone cave formed off the beaches of Belize, they call it the great blue hole and it is an underwater siphonimportant not only for the practice of extreme sports but also scientifically, as it has witnessed the change of habitat for more or less a thousand years; at that time, the hole was dry and filled with water so slowly that fossils were preserved insidesuch as turtles, crocodiles, birds, plants that still have their chlorophyll despite the time, and human remains from 1,500 years ago.
In distant Siberia, some holes appeared that are the newest and most mysterious, after discovering the first one, which has a lake inside it, two smaller ones appeared but as enigmatic as the first ones, were apparently initiated by subterranean collapse from melting permafrost, a type of ever-frozen soil in the Siberian tundra; there are many versions about it.
In Yellowstone there were explosions and telluric phenomena, the last one was 642,000 years ago more or less; the lava under the earth’s crust erupted, which resulted in the eruption of thousands of cubic kilometers of stones and the magmatic chamber sank, forming a hole that has been a kind of caldera, a very visited site in the park; later there were other minor and multiple eruptions that partially filled said caldera, but the steep edges are recognizable; volcanism is still very active in Yellowstone, where there are hot springs and about 300 geysers, which proves the strength of underground activities.
It is believed that 2500 wells have originated from 1970 to today in the Dead Sea and approximately thousand of them in the last 15 years; Due to the drainage, the fresh water that accesses it quickly dissolves much of the salt that is concentrated in the area around the lake, this causes the weakening and collapse of the land surface on the shores of this closed sea, which creates more holes all around.
The locals in the Karakum desert in Turkmenistan call one of the most fascinating holes on the planet as the door to hell, where gas was discovered in its subsoil, when drilling, the machine collapsed and created a huge hole through which fire is generated until today, its beauty is determined by the unusualness of the landscape.
When planning your vacations, you could take these beauties into account and prepare to visit these unusual destinations, where you can enjoy different environments prepared to offer the same comfort as more promoted sites, but with less natural quality.
